Apocalyptic Wasteland: Is Fusion the Most Useless Profession?

[Apocalypse + System + Pet Beast + Counterattack + Home] The wasteland suffered a cataclysm, my powers were awakened, and I became the fusion person recognized as the "most useless profession". The first fusion failed and my genes were on the verge of collapse. Everyone said I might as well become a purifier. Until I activated the "Gene Adaptation System". The genetic map distributed daily guides me in hunting highly adaptable mutated creatures: lightning rabbits, crystal core beasts, volcanic dragons... Since then, I have embarked on a path that no one dared to imagine - 100% risk-free fusion, swallowing thousands of genes, and evolving exclusive magical skills! While others were still betting their lives on a fusion, I was already carrying the Eternal Level Symbiotic Beast, controlling the thunder and desert sand. In the league competition, I swept the field; deep in the wasteland, I hunted down lords. All forces regard me as an alien that must be controlled or eliminated, but the ancient ruins show that I am the key to restarting civilization. The crisis of genetic collapse is approaching, and I just want to build a real home for the people I love in this broken world. They call me a monster, and I will be the only god in the new era.
